In the ferrox test, benzene would not show any result because benzene is not reactive with the reagents used in the test. The ferrox test is typically used to detect the presence of phenol or compounds with a phenolic group, which can form colored complexes with the reagents. Benzene lacks this functional group and therefore does not participate in the reaction.

Why is the xanthoproteic test for phenol negative?
I reckon the answer would be that phenol has a hydroxyl group (-OH) which is bonded to a phenyl ring. It yields the same positive result like tyrosine which has a hydroxyl group bonded to its phenyl ring.
What would the result of crackers in benedicts test?
Turns blue black

Can semen affect pregnancy test result?
No, semen should not affect the result of a pregnancy test. Pregnancy tests detect the presence of the hCG hormone in urine, which is produced by the placenta in response to a fertilized egg implanting in the uterus. Semen does not interfere with this process.
Would glucose give a positive result with the Biuret test?
No, glucose would not give a positive result with the Biuret test. The Biuret test is specific for detecting proteins, not sugars like glucose. It works by reacting with peptide bonds in proteins to form a colored complex.
Is acetaminophen will give positive result to Lassaigne's test and ferrox paper test?
yes
What is a ferrox test?
A test for the presence of oxygen for organic compounds which contain the element carbon.
What is the result when benzene gets ignited and undergoes the Baeyer's test?
Benzene is flammable so when it is ignited fire will be produced and then black soot will appear. When benzene undergoes Baeyer's test, the process is slow but it will turn brown.
Does lactose can give a positive result in xanthoprotein test?
nitration of the benzene ring and gives positive
What tripeptide will give a positive xanthoproteic test?
Phenylalanine. When phenylalanine is subjected to a xanthoproteic test, it will produce a yellow solution due to the reaction of the aromatic ring with nitric acid, indicating the presence of phenyl group in the tripeptide.
What is a benzene blood test?
A blood test for benzene is one method that might be used to determine if an individual has been exposed to benzene and how much he might have been exposed to. As benzene leaves the blood quickly, another or other tests might also be considered.
What if you prefer a test result?
This would depend on what kind of test result is needed: a physical exam result, a school test, a blood test, etc. If it concerns a test result due to blood or other test, you can request the result from the family physician. If the test result concerns education, this is up to the teacher or professor but you can ask..
What are the equations of hexane benzene and acetylene in the Baeyer's test?
Hexane and benzene do not react in the ignition test. Only acetylene does. Acetylene has a triple bond if equivalent amount of KMnO4 is used. The equation is HCCH + KMnO4 -> HC (OH) = CH(OH).
Why doesn't benzene react in the bromine test and the baeyer's test?
due to extensive delocalization of pie-electrons of benzene , it do not undergoes Bayer's and bromine test. 6 carbon nuclei hold the pie electronic cloud which make it difficult for an electrophile to attack.
Is a HIV test done at 85 day after the intercourse and the result is negative is that result is valid?
Yes, it would be a valid test.
Can semen affect pregnancy test result?
No, semen should not affect the result of a pregnancy test. Pregnancy tests detect the presence of the hCG hormone in urine, which is produced by the placenta in response to a fertilized egg implanting in the uterus. Semen does not interfere with this process.
